体外研究 (In Vitro) |
Lesinurad 是一种新型 SURI(选择性尿酸重吸收抑制剂)。 lesinurad 的 Km 值分别为 0.85 和 2 µM,被发现是肾脏转运蛋白有机阴离子转运蛋白 (OAT1) 和 OAT3 的底物 [1]。 OAT 和 URAT1 抑制剂 lesinurad (RDEA594) 会增加近端肾小管的尿酸盐排泄 [2]。 Lesinurad (RDEA594) 是一种潜在有效的降尿酸药物,可通过抑制尿酸再摄取来抑制 CYP2C9 和 CYP2C8,并具有很强的 p450 特性,IC50 值分别为 14.4 μM 和 16.2 μM。对于 CYP1A2、CYP2C19 和 CYP2D6,lesinurad 的 IC50 大于 100 µM [3]。

体内研究 (In Vivo) |
与其前药 RDEA806 相比,lesinurad (RDEA594) 表现出更优异的药代动力学。 100 mg Lesinurad 的药理作用与 300-800 mg 单剂量 RDEA806 的药理作用相当[3]。

Solubility in Formulation 1: 2.5 mg/mL (5.86 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (5.86 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More
Solubility in Formulation 3: 2.5 mg/mL (5.86 mM) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution; with ultrasonication. 1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液)); 2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方): 10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline); 假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL; 3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例; 4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶; 5、为保证最佳实验结果,工作液请现配现用! 6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们; 7、 以上所有助溶剂都可在 Invivochem.cn网站购买。 |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
